Electric water heater is used in a variety of common everyday household and commercial needs, from washing dishes to cleaning floors, hot water. The basic components of electric water heater includes; glass or ceramic lined steel tanks to protect against corrosion, foam for insulating purposes, and low watt-density heating elements. Electric water heater problems can be irritating as the cost of repair works is high. Knowing how to troubleshoot an electric water heater saves money and time. With the right knowledge you can fix it anytime. Turn electrical power off before attempting to repair, replace or disconnect any electrical equipment.
Lack of Function
Inspect the circuit breaker or fuses to make sure that a power surge on the same circuit did not trigger the breaker to flip. Often, repairing starts with a simple reset of the single breaker. After you switch it totally to the "off" position, it can be flipped back to power on. If you identify that a current is reaching the water heater, it should turned back to the "off" position and a sign must be provided alerting others not to flip the breaker back on. Next, you should remove the thermostat cover on the heater and check for terminals marked "L1" and "L2." A voltage meter will help to determine whether an existing is reaching these terminals. By manually resetting may fix the issue as detailed in the owner's manual for the heater.
Electric Water Heater Leaks
Water leaking from the bottom of the water heater usually means there is a crack in the internal tank and your water heater need some inspection or replacement. Most leaks are caused by leaking connections at the hot water outlet or cold water inlet. Occasionally, leaks can be found coming from a fitting such as around the Temperature and Pressure Relief Valve or around one of the heating elements. Leaking fittings can often be tightened or repaired. Determine where the leakage originated. The leaks typically start as a pinhole leakage and get worst as the days go on. Water leaks can be triggered by leaking valves, connections or from the tank itself. If however, the tank has rusted through and is leaking then its replacement time.
No Hot Water
If you are not getting any hot water, it’s possible that your breaker may have tripped or the water heater has a faulty thermostat. First push the reset button on the high-temperature cutoff and test the thermostats and replace if faulty. Check the breaker box to see if the water heater breaker has tripped. If the breaker is in place most often a water heater part has failed. If there is not enough hot water, adjust the thermostat settings. As needed, reset, test and replace thermostats and heating elements if faulty. If the water is too hot, adjust the thermostat settings and reset. Test and replace the thermostat or high-limit cutoff.
To drain the sediment from your electric water heater, first you must switch off the power to the electric water heater and turn off the cold inlet valve. The cold inlet valve should be located on the left on top of your electric water heater. Turn on the hot water in a sink closest to the water heater, and attach a hose to the water heater outlet valve. The outlet valve should be behind the access panel at the base of the water heater. After placing the end of the drain hose in a floor drain, working sump pump pit, or utility sink, open the drain valve, and allow the water heater to fully drain. Don't be surprised if the draining process takes a few hours. After the water heater has fully drained, open the cold water inlet valve once again, and allow cold water to run through the water heater until the water is clean and clear.
Noisy Hot Water Pipes
If you're hearing mysterious noises coming from your water pipes, pay close attention to your noisy pipes. If your pipes are noisy only when the hot water is running, chances are the water temperature is set too high. Steam in the pipes will cause the pipes to become noisy. Besides hushing noisy pipes, turning down the temperature of your hot water will help save money on your electric bill, and you'll reduce the danger of problems such as scalding.
